Finite Element Analysis of Guyed Masts under Seismic Excitation
Adlin Nelofer J, N Saravana Kumar
Abstract: The seismic response of guyed masts is analyzed using the Finite element program ABAQUS in terms of their structural behavior and input seismic accelerograms. Detailed numerical simulations of four masts with varied parameters involving guy cables equally spaced at different stay levels are modeled to explore the dynamic behavior of mast under harmonic seismic ground motion. Modal dynamic and steady state dynamic analysis are carried out to analyze the behavior of guyed mast during drastic seismic movements. Displacement, base shear and axial force at various levels of guyed mast are computed and validated. The seismic response of precedent guyed masts isolated with a Friction Pendulum System (FPS) is examined under the same input seismic accelerograms and compared with the procured results. This evolution will concede towards an advanced resilient rational model for simplified seismic analysis of guyed masts.
